I got to have a quick go the other evening. A quick blast through For Whom The Bell Tolls and Call of Ktulu. I'm surprised by the fuzz side being a pretty decent fuzz, wasn't paying too much attention to the 2 different modes. The wah is really nice. There's three aspects I need to get used to:
1) the travel of the pedal isn't very far compared to a Dunlop or the expression pedal for my Zoom B3
2) you need to keep the pedal very slightly down or it bypasses the wah
3) the delay in the wah being bypassed, I guess that's so it's not continually switching in and out as you rock the pedal.
But over all I'm really happy with it. Plus it's freed up a space on the pedal board now I don't need the B3.
